The house changes hands. The knowledge usually doesn't.
Keys, a garage remote, and a drawer of manuals for appliances that left with the seller. Everything that made the place make sense walks out the door.
A buyer inherits a building and none of its history. Which valve is the main shutoff. Which breaker is the one that trips. What the hall was painted, and in what finish. Who last serviced the furnace, and whether the warranty transfers. The seller knew all of it on Tuesday and is unreachable by Friday.
If you are selling
The buyer report collects what you have entered: rooms, systems, shutoffs, appliances with their models and serials, service history, warranties, and the documents attached to each, into one record you hand over at closing.
It costs you an afternoon and it ends the six months of texts that otherwise follow a sale. It is also, quietly, a demonstration that the place was looked after. We make no claim about what that is worth in price or days on market, because we have no evidence for one.
If you are buying
Start the record during the inspection, while a professional is walking the house telling you where things are. That is the one hour in the life of a home when someone is paid to explain it to you, and almost none of it gets written down. Photograph the plates. Note the shutoffs. The inspection report goes in as a document.
Ask the seller for their record. If they do not have one, you are starting the first.
For agents and inspectors
A record handed to a client at closing outlasts the sale, and it has your name on it. If you place records for clients regularly, the professional channel is built for that.
What happens to the record afterwards
A home record should survive its author. Ownership transfers with the property, the export is always complete and includes your files, and if this service ever winds down you get 90 days' notice and a bulk download. That is written down in our Data Promise rather than left to trust.
Free for your own home, however long you stay in it.
